DETAILED DESCRIPTION

[0028] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0029] Example 1

[0030] A grinding device for producing ultrafine heavy calcium carbonate, such as Figure 1-Figure 2 As shown, it includes a motor 1, a reducer 2, a grinder 3, a base 4, a cooling mechanism 5 and a cooling mechanism 6. The top of the base 4 is connected to the grinder 3 by bolts, the upper part of the grinder 3 is connected to the motor 1 by bolts, the upper part of the grinder 3 is connected to the reducer 2, the output shaft of the motor 1 is connected to the output shaft of the upper part of the reducer 2, the output shaft of the lower part of the reducer 2 is connected to the driving shaft of the grinder 3, the reducer 2 is provided with a cooling mechanism 5, and a cooling mechanism 6 is provided between the grinder 3 and the lower part of the base 4; Figure 1-Figure 3As shown, the cooling mechanism 5 includes a first water tank 51, a tension spring 52 and a first fixed block 53. The first fixed block 53 is connected to the front side of the top of the reducer 2. The first water tank 51 is slidably connected to the first fixed block 53. The first water tank 51 covers the front, left and right parts of the reducer 2. A tension spring 52 is connected between the upper rear part of the first water tank 51 and the front side of the first fixed block 53. The tension spring 52 is wound around the upper part of the first water tank 51; Figure 1 , Figure 4 and Figure 5 As shown, the cooling mechanism 6 includes a cylinder 61, a water storage frame 62 and a first fixed rod 63. The cylinder 61 is connected to the lower right portion of the base 4 by bolts, the first fixed rod 63 is connected to the left portion of the grinder 3, the water storage frame 62 is slidably connected to the outer side of the grinder 3, the left portion of the water storage frame 62 is slidably connected to the first fixed rod 63, and the right portion of the water storage frame 62 is connected to the top of the telescopic rod of the cylinder 61.

[0031] When producing ultrafine heavy calcium carbonate, the calcium carbonate material can be first poured into the grinding chamber of the grinder 3, and then the motor 1 is started, and the speed is reduced by the reducer 2. Then the output shaft of the reducer 2 rotates to drive the driving shaft of the grinder 3 to rotate, providing grinding power for the grinder 3, thereby grinding the calcium carbonate material to obtain ultrafine heavy calcium carbonate. During the operation of the reducer 2, the reducer 2 is prone to heat up. At the same time, the calcium carbonate material is ground in the grinding chamber of the grinder 3, and the temperature of the grinding chamber will rise. In order to extend the life of the reducer 2 and reduce the risk of expansion and explosion of the grinder 3, the grinding chamber and the reducer 2 can be cooled. First, inject ice water into the first water tank 51 and the water storage frame 62. The first water tank 51 will cool down the reducer 2, and the reducer 2 will vibrate during operation. During the vibration of the reducer 2, the tension spring 52 will deform adaptively, and under the action of the tension spring 52, the first water tank 51 can be close to the reducer 2, so that the reducer 2 can be kept cooled. In addition, the telescopic rod of the cylinder 61 can be controlled to move telescopically to drive the water storage frame 62 to move up and down. The water storage frame 62 will cool down the grinder 3, thereby reducing the temperature in the grinding chamber and avoiding thermal expansion. The motor 1 and the cylinder 61 can be turned off when not in use.

[0032] Example 2

[0033] On the basis of Example 1, Figure 1 and Figure 6As shown, a heat exchange mechanism 7 for exchanging heat with water is also included, and the heat exchange mechanism 7 includes a hose 71, a second water tank 72, a return spring 73 and a second fixed rod 74. The left and right sides of the upper rear portion of the grinder 3 are connected to the second fixed rods 74, and the second water tank 72 is slidably connected between the second fixed rods 74. The return spring 73 is connected between the left and right sides of the upper portion of the second water tank 72 and the upper portion of the second fixed rods 74. The return spring 73 is wound around the second fixed rods 74, and a hose 71 is connected between the left and right sides of the front portion of the second water tank 72 and the rear portion of the first water tank 51.

[0034] Inject part of the ice water into the second water tank 72 in advance, and the water level of the ice water in the second water tank 72 is lower than the position of the hose 71, so the ice water in the second water tank 72 will not flow into the first water tank 51 through the hose 71, and the ice water in the first water tank 51 will increase in temperature and become hot water when cooling the reducer 2. In order to achieve the purpose of heat exchange with hot water, the second water tank 72 can be moved downward, and the return spring 73 is stretched. When the position of the second water tank 72 is lower than the first water tank 51, the hot water in the first water tank 51 will flow into the second water tank 72 through the hose 71, so that the hot water and the ice water are mixed together, thereby reducing the temperature of the hot water and achieving the purpose of heat exchange. Then move the second water tank 72 upward. When the position of the second water tank 72 is higher than the first water tank 51, the water after heat exchange in the second water tank 72 flows back to the first water tank 51 through the hose 71, and the return spring 73 is compressed. In this way, the heat exchange effect can be achieved, and the efficiency of cooling the reducer 2 can be improved.

[0035] like Figure 1 , Figure 7 and Figure 8 As shown, a heat dissipation mechanism 8 for dissipating heat from the water storage frame 62 is also included. The heat dissipation mechanism 8 includes a rotating heat absorbing member 81, a toggle member 82 and a second fixed block 84. The rotating heat absorbing member 81 is rotatably connected to the right side of the top of the water storage frame 62. A threaded groove is provided on the outer side of the upper portion of the rotating heat absorbing member 81. The second fixed block 84 is connected to the upper right portion of the grinder 3. The toggle member 82 is slidably connected to the inside of the second fixed block 84. The lower portion of the toggle member 82 is slidably connected to the threaded groove.

[0036] like Figure 7 and Figure 8 As shown, a first pressure spring 83 is also included. The first pressure spring 83 is connected between the upper part of the toggle member 82 and the top of the second fixed block 84 , and the first pressure spring 83 is wound around the upper part of the toggle member 82 .

[0037] The upward movement of the water storage frame 62 drives the rotating heat absorption member 81 to move upward, and the upward movement of the rotating heat absorption member 81 drives the threaded groove to move upward. Under the action of the toggle member 82, the rotating heat absorption member 81 is driven to rotate to the right and open, and the rotating heat absorption member 81 rotates to the right and expands to dissipate the absorbed heat. When the toggle member 82 is located at the lowest position of the threaded groove, the threaded groove will continue to move upward with the water storage frame 62, and the threaded groove will push the toggle member 82 forward, so that the first pressure spring 83 is stretched. When the water storage frame 62 moves downward, it will drive the rotating heat absorption member 81 to move downward, and the threaded groove will move downward accordingly. Under the action of the first pressure spring 83, the toggle member 82 is driven to move downward and reset. Moreover, under the cooperation between the toggle member 82 and the threaded groove, the rotating heat absorption member 81 can be swung to the left and reset to fit the right wall of the water storage frame 62 again, so that the heat of the water storage frame 62 can be absorbed, thereby achieving the purpose of dissipating heat from the water storage frame 62.

[0038] like Figure 1 and Fig. 9 As shown, it also includes an air cooling mechanism 9 for cooling the water storage frame 62 by blowing air, and the air cooling mechanism 9 includes a fixing frame 91, a fan 92 and a second pressure spring 93. The fixing frame 91 is slidably connected to the first fixing rod 63, the bottom of the fixing frame 91 is connected to the left side of the top of the water storage frame 62, the second pressure spring 93 is connected between the top of the fixing frame 91 and the upper part of the first fixing rod 63, and the fan 92 is connected to the left side of the top of the fixing frame 91 by bolts.

[0039] The fan 92 is started, and the fan 92 blows air to the left side of the water storage frame 62. When the water storage frame 62 moves upward, the fixing frame 91 and the fan 92 are driven to move upward. The second pressure spring 93 is compressed. When the water storage frame 62 moves downward, the fixing frame 91 and the fan 92 are driven to move downward under the action of the second pressure spring 93. The fan 92 continuously moves up and down to blow air up and down on the left side of the water storage frame 62 to achieve the purpose of cooling and heat dissipation. The fan 92 can be turned off when not in use.

[0040] like Figure 1 and Fig. 9 As shown, it also includes a spraying mechanism 10 for spraying water for cooling, the spraying mechanism 10 includes a third water tank 101, a spray gun 102 and a toggle frame 103, the left part of the fan 92 is connected to the third water tank 101 by bolts, the front and rear sides of the right part of the third water tank 101 are connected to the spray gun 102, and the upper left part of the grinder 3 is connected to the toggle frame 103.

[0041] Water is injected into the third water tank 101, and the fan 92 moves up and down to drive the third water tank 101 to move up and down. The third water tank 101 drives the spray gun 102 to move up and down. When the spray gun 102 moves upward and contacts the toggle frame 103, the spray gun 102 sprays water to the left side of the grinder 3, so that the grinder 3 can be cooled down. When the spray gun 102 moves downward and separates from the toggle frame 103, the spray gun 102 stops spraying water.
